Disclosed is an electrode probe (1) and body fluidnexamination equipment enabling examination of a tracenamount of body fluid. The electrode probe (1) comprises anninsulating needle member (2,12), a working electrode lead (3)ndisposed in the needle member (2,12), a working electrode (13a) whosenlead is protruding outside from the needle member (2,12), ancounter electrode (15) disposed on the surface of the needlenmember (2,12), a lead (14) connected to the counter electrode, and anreagent layer (17) disposed in contact with or in the vicinitynof the working and counter electrodes of the electrodensystem. When a trace amount of body fluid leaking on thenskin surface is brought into contact with the reagentnlayer (17), the reagent layer dissolves which results innelectron transfer whereby information about thenconcentration of analyte in the body fluid can be obtainednfrom the electrode system. |
